Our brains shape individual differences of perception by responding to sensory inputs differently across individuals. This study aimed to develop a computational system that estimates such individual differences of perceptual information in the brain with no brain measurement. For this purpose, we employed the method we previously developed to predict brain response to arbitrary movie inputs using convolutional neural networks. This method requires no brain measurement once computational models for predicting brain response are trained using measured brain data. We evaluated the inter-subject dissimilarity of perceptual information decoded separately from predicted and measured brain responses to movies. We found that the inter-subject dissimilarity decoded from predicted response was significantly correlated with that decoded from measured response for 80/86 items to be decoded. Our finding suggests that our computational system can estimate individual differences of perceptual information in the brain. |
